The title compound (C25H24N4O3) has been prepared by the cyclocondensation of 5-amino-3-methyl-1-phenypyrazol, m-nitrobenaldehyde and dimedone in glycol under microwave irradiation without catalyst. The crystal structure was determined by single-crystal X-ray diffraction to be orthorhombic, space group Pbca with a = 16.3331(10), b = 13.8329(9), c = 19.4163(12) (A), V= 4386.8(5) (A)3, Z = 8, Dc = 1.298 g/cm3,μ = 0.087 mm-1, F(000) = 1808, Mr = 428.48, the final R =0.0519 and wR = 0.1019. X-ray analysis revealed that the pyridine ring is of boat conformation and the six-membered ring fused with it adopts twist boat conformation.
